Embodiment Construction

[0037] Referring now to the drawings, systems and methods for determining an accumulation control state for mapping logical block addresses (LBAs) to physical block addresses (PBAs) are disclosed. An exemplary system includes a bi-tone network including a first switch and configured to receive a first randomly ordered list and a random switch setting at which the random switch setting is used to determine the first random ordered list permutation, where the permutation contains the second randomly sorted list, and outputs the second randomly sorted list. The exemplary system also includes a bi-tone sorter that includes a second switch and is configured to receive a second random sorted list, sort the second random sorted list, and output the second switch for effecting the sorting. setting, wherein the second switch setting defines an accumulation control state; and an access network configured to use the accumulation control state to determine a PBA of a non-volatile memory (...

Abstract

Systems and methods for determining an accumulation control state for mapping logical block addresses (LBAs) to physical block addresses (PBAs) are disclosed. One such system includes a dual tone network comprising a first switch and configured to receive a first random ordered list and a random switch setting at which the random switch setting is used to determine the first random ordered list A permutation of , wherein the permutation comprises a second randomly sorted list and outputs a second randomly sorted list; a bitone sorter comprising a second switch and configured to receive a second randomly sorted list, and to output the second randomly sorted list the sorted list is sorted and outputs a setting of a second switch for effecting the sorting, wherein the second switch setting defines an accumulative control state; and an access network configured to use the accumulative control state to determine the nonvolatile memory (NVM) PBA to enable data access of the corresponding LBA.
